            <p>太阳是太阳系的中心天体，也是地球上所有生命的能量来源。它主要由氢和氦等气体组成，通过核聚变过程产生巨大的能量。太阳的表面温度约为5800K，表面活动如太阳黑子、耀斑等会对地球产生一定影响。</p>

            <h2>太阳的结构</h2>
            <p>太阳主要由核心、辐射层、对流层和光球组成。核心是太阳能量的来源，其中核聚变反应不断释放出能量。辐射层和对流层负责将能量传输到太阳表面。光球是太阳的表面，也是我们看到的太阳外观。</p>

            <h2>太阳活动</h2>
            <p>太阳表面的活动主要包括太阳黑子、日冕物质抛射和耀斑等。太阳黑子是表面温度较低的区域，通常伴随着磁活动。日冕物质抛射是太阳表面物质向太空喷射的现象，而耀斑则是太阳表面释放的强烈能量。</p>
